Newest underwater strobe from AOI (in white color). This model has everything you need: InTeLi™ Mode, TTL - RC - Manual and HSS. A perfect and easy to handle, compact strobe with a GN of 22.

UCS-Q1i: Powerful and Compact

The UCS-Q1i is a powerful and compact strobe that redefines underwater lighting technology. Building on the success of the UCS-Q1 and UCS-Q1RC, AOI Ltd continues to push the boundaries of underwater imaging innovation.

A Legacy of Excellence

The award-winning UCS-Q1 became a favorite among beginners thanks to its advanced features typically found in more premium models. The UCS-Q1RC introduced TTL integration for OM System cameras, delivering a seamless experience in both performance and design.

Innovation Through AOI InTeLi™ Mode

AOI Ltd further strengthened its reputation with the launch of the UIS-P1, which introduced AOI InTeLi™ Mode — a next-generation system specifically optimized for underwater photography.

Introducing the UCS-Q1i

The new UCS-Q1i combines the best features of the UCS-Q1 and UIS-P1. It inherits AOI InTeLi™ Mode, offering precise and consistent TTL exposure across a wide range of camera systems, surpassing traditional S-TTL and TTL performance. This intelligent mode automatically adjusts to camera settings, ensuring exceptional accuracy in exposure control.

Refined Macro Capabilities

Included in AOI InTeLi™ Mode is i-Macro Mode, designed to optimize light output for close-up shooting. Underwater photographers can capture intricate details with exceptional clarity, making beautifully lit macro shots easier than ever. AOI InTeLi™ Mode supports Sony TTL and i-Macro, OM System RC TTL and i-Macro, as well as TTL HSS and M-HSS modes.

Unmatched Performance

Most notably, the UCS-Q1i remains the brightest strobe in its class, with an impressive Guide Number 22 (GN22) at ISO100 — delivering powerful underwater illumination. Like the UIS-P1, it also supports High Speed Shutter (HSS) compatibility with Sony cameras, enabling photographers to freeze fast-moving underwater scenes with precision and clarity.
